We are remembering those who served.
It was an honour to meet this lady ahead of VE Day today, whose work at Bletchley Park was vital to our wartime effort. Britain's code and cipher school in the iconic huts and blocks of Bletchley, a Victorian mansion, served as the UK's secret codebreaking headquarters during World War Two.
Coded messages sent by the Nazis, including orders from Adolf Hitler, were intercepted and then translated.
Gwenfron worked on the Typex machine, a cipher machine used to encrypt and decrypt messages, including those intercepted from German Enigma machines.
We were privileged to listen to her memories of her time in Bletchley and signing the Official Secrets Act.
Gwenfron was 18 when she was called for an interview in the Port Talbot Labour Exchange where she was asked how she would support the war effort.
She wanted to be a nurse, but was told she was too slight for the role.
This led her to London - a city she had never been to before - where she was assigned to Bletchley Park.
Gwenfron said she was "proud" of her service and even got promoted while working there from 14 August 1944 to 26 September 1945.
At a time when fears about German spies were heightened, you could only talk to people you "worked with, or you lived with," according to Gwenfron.
She said she never heard the air raid siren go off at Bletchley Park which contrasted with her time in Wales.
"They kept away. At home it used to go off quite often. Especially when they were going over Swansea," she said.
